No identifier specified for entity

[newguy]

I got an error saying

org.hibernate.AnnotationException: No identifier specified for entity: MyEntity.

when I deploy my roo generated war file to Tomcat 6.0.

My project is using Spring 3.0 + Hibernate 3.4.

but in MyEntity_Roo_Entity the code is as below:

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "id")
    private Long MyEntity.id;
    
    @Version
    @Column(name = "version")
    private Integer MyEntity.version;
    
    public Long MyEntity.getId() {
        return this.id;
    }
    
    public void MyEntity.setId(Long id) {
        this.id = id;
    }

What is wrong with my code? The primary key has been defined in MyEntity.id. Why does it show that error?

There does not appear to be anything wrong in you what you have listed. You mentioned you are using Hibernate 3.4 and I have seen this problem before when mixed versions of Hibernate jars are used. Roo has used Hibernate 3.6.x for a while now so make sure that all the Hibernate jars in your classpath have exactly the same version number.

Thanks Alan I am also aware of that. But when I search the dependency in Eclipse the latest version of these two dependencies available is 3.4.0.GA.

com.springsource.org.hibernate.annotations
com.springsource.org.hibernate.ejb

But I did notice that there are multiple but different versions of com.springsource.org.hibernate jar files in the lib folder of my Tomcat server.
